- RF simulator for performance validation over a multitude of orbits and operational scenarios
Manufacturing
OrbFIX is manufactured, integrated and tested in Europe.
Besides internal qualification, user agreed qualification campaigns can be optionally performed.
Lead time is typically 4 - 8 weeks for a small number of units.
Testing & qualification
ECSS based qualification campaigns were performed at various development stages.
Export control
OrbFIX is a European product using European technologies and it is ITAR free.
OrbFIX is a dual-use item and end-use declaration of no military use and no export to sanction countries needs to be provided.
